Vaginal prolapse - Causes, Treatment & When to See a Doctor

What is Vaginal Prolapse?

Vaginal prolapse, also called pelvic organ prolapse (POP), occurs when the walls of the vagina lose their normal support and descend toward or outside the vaginal opening. The structures that normally hold the vagina in place—muscles, ligaments, and connective tissue—become stretched, weakened, or torn, allowing the vaginal canal to sag. In more severe cases, part of the vagina may protrude through the introitus (the opening of the vagina), which can be visible as a bulge.

Vaginal prolapse is a common condition, affecting up to 50 % of women over 50 to some degree, though many are asymptomatic and never seek treatment <sup>[1]</sup>. It can occur alone or together with prolapse of other pelvic organs such as the bladder (cystocele), uterus (uterine prolapse), or rectum (rectocele).

Common Causes

The exact cause is usually a combination of factors that stress or damage the pelvic support structures. The most frequent contributors include:

• Childbirth, especially vaginal delivery – Stretching and tearing of pelvic muscles and fascia.
• Multiple pregnancies – Repeated hormonal and mechanical strain.
• Age‑related weakening – Decline in collagen and muscle tone after menopause.
• Chronic increased intra‑abdominal pressure – Chronic cough, constipation, or heavy lifting.
• Obesity – Excess weight adds constant pressure on the pelvic floor.
• History of pelvic surgery – Hysterectomy, bladder sling, or other pelvic procedures can disrupt support.
• Genetic connective‑tissue disorders – Ehlers‑Danlos syndrome, Marfan syndrome, or other collagen defects.
• Hormonal changes – Decreased estrogen after menopause reduces tissue elasticity.
• Radiation therapy to the pelvis – Can damage connective tissue.
• Neurologic conditions – Stroke, spinal cord injury, or multiple sclerosis that affect muscle control.

Associated Symptoms

The degree of prolapse often dictates the symptoms. Commonly reported complaints include:

• A feeling of heaviness, fullness, or pressure in the pelvis.
• Visible bulge or lump at the vaginal opening, especially when standing or straining.
• Discomfort or pain during sexual intercourse (dyspareunia).
• Urinary problems: frequency, urgency, incontinence, or difficulty fully emptying the bladder.
• Problems with bowel movements: constipation, straining, or feeling of incomplete evacuation.
• Lower back or hip pain caused by altered posture.
• Feeling of "something falling out" that can be more noticeable after coughing or lifting.
• Skin irritation or ulceration if the prolapsed tissue rubs against clothing.

When to See a Doctor

Although mild prolapse may be managed with lifestyle changes, you should schedule an appointment if you notice any of the following:

• New or worsening bulge that protrudes beyond the vaginal opening.
• Painful urination, recurrent urinary tract infections, or new onset urinary retention.
• Severe constipation, inability to pass stool, or feeling of rectal pressure.
• Pain during sexual activity that interferes with intimacy.
• Skin breakdown, bleeding, or discharge from the prolapsed tissue.
• Rapid progression of symptoms over weeks to months.

Early evaluation allows for conservative measures or minimally invasive procedures that are often more effective when the prolapse is caught early.

Diagnosis

Evaluation of vaginal prolapse is typically performed by a primary‑care physician, gynecologist, or urogynecologist and includes the following steps:

1. Medical History – Detailed discussion of obstetric history, chronic cough or constipation, prior surgeries, and symptom timeline.
2. Physical Examination
   • Pelvic exam in both supine (lying) and upright positions; the clinician may ask you to “perform a Valsalva maneuver” (push as if having a bowel movement) to reveal the extent of descent.
   • Grading systems such as the Pelvic Organ Prolapse Quantification (POP‑Q) system assign a numerical stage from 0 (no prolapse) to 4 (complete eversion).
3. Imaging (if needed)
   • Trans‑perineal or translabial ultrasound to visualize pelvic floor muscles.
   • Dynamic MRI for complex cases or when surgical planning is required.
4. Urodynamic testing – May be ordered if urinary symptoms are prominent, to assess bladder function.
5. Additional labs – Generally not required unless infection, skin breakdown, or other systemic issues are suspected.

Treatment Options

Treatment is individualized based on severity, symptoms, age, activity level, and personal preferences. Options range from conservative self‑care to surgical correction.

Conservative (Non‑Surgical) Management

• Pelvic floor muscle training (PFMT) – Often called Kegel exercises; when performed correctly, they can strengthen support and reduce mild prolapse. A study in *Obstetrics & Gynecology* showed a 30‑40 % improvement in stage I‑II prolapse after 12 weeks of supervised PFMT <sup>[2]</sup>.
• Pessary devices – A removable silicone or acrylic device placed in the vagina to hold walls in place. Pessaries are especially useful for women who wish to avoid surgery or are not surgical candidates.
• Hormone therapy – Local estrogen cream (e.g., estradiol 0.01%) can improve tissue quality in post‑menopausal women.
• Weight management – Reducing BMI by 5–10 % can lower intra‑abdominal pressure and relieve symptoms.
• Lifestyle modifications – Treat constipation (high‑fiber diet, stool softeners), quit smoking (reduces chronic cough), and avoid heavy lifting (>10 lb).

Medical‑Surgical Options

• Mid‑urethral sling – Primarily treats stress urinary incontinence but can provide additional support for mild prolapse.
• Transvaginal repair – Suturing or mesh reinforcement of the vaginal wall through an incision in the vagina. Modern FDA‑cleared mesh is used sparingly due to previous complications.
• Laparoscopic or robotic sacrocolpopexy – A mesh strip is attached to the vaginal apex and anchored to the sacrum via a minimally invasive abdominal approach; considered the gold standard for uterine or vaginal vault prolapse in many centers.
• Uterine-preserving procedures – Vaginal hysteropexy or sacrohysteropexy keep the uterus intact for women who desire future fertility or wish to retain their uterus.
• Colpocleisis – A “partial closure” of the vagina used in older, non‑sexually active women; it eliminates the prolapse but permanently occludes the vaginal canal.

Post‑operative rehabilitation with PFMT is recommended regardless of the surgical technique.

Prevention Tips

While not all cases are preventable, many risk factors can be mitigated with proactive habits:

• Perform daily Kegel exercises – Aim for three sets of 10‑15 squeezes, holding each contraction for 5–10 seconds.
• Maintain a healthy weight – Aim for a BMI < 25 kg/m² if possible.
• Eat a high‑fiber diet – 25‑30 g of fiber per day to prevent constipation and straining.
• Stay hydrated – At least 8 cups of water daily to keep stools soft.
• Exercise regularly – Low‑impact activities such as walking, swimming, or yoga strengthen core muscles without over‑loading the pelvic floor.
• Quit smoking – Reduces chronic cough and improves overall tissue healing.
• Use proper lifting techniques – Bend at the knees, keep the back straight, and engage the core when lifting objects.
• Schedule regular pelvic exams – Early detection of subtle descent allows for timely, non‑surgical interventions.
